My thought is that I'm not convinced, since I personally don't have any experience of loving God without also having faith and hope in Him. So I'm not sure that's a good reason for me personally to believe Love is greater than Faith and Hope.
Also, it seems to me someone might have little love for God but put faith in Him simply out of guilt and fear of judgement. For that person, Faith would exist apart from Love. But does this make Faith greater?
I'm thinking, then I need something more convincing for me to be certain Love is the greatest. You might have what I need. For you said, "God is love." Would you also say God isn't Faith or Hope?
I think you are blessed for not having doubts. I even doubted God's love at one time in my life. Like the prodigal son, he was foolish and doubted his Father loved him, and thought he might have to beg to be his father's servant. But his father loved him all along, even when the son thought maybe he didn't.
Yes, the Bible says God is love, not faith and not hope.
Also, "Perfect love casteth out fear."
God's love for us is perfect, no selfishness in it, as well as being complete. Perfect in both senses. Never failing, always forgiving.
It is love for us that caused Him to come and die for us.
Romans 5:8 "But God commendeth His love toward us, in that, while we were yet sinners, Christ died for us."
I think what I am clumsily getting at here is this: God has no faith or hope in us. But He loves us with an all consuming, unconditional, perfect love.
Love is greater, because God is love.
We have hope and faith, and our love is a mere reflection of His own. Like our love is moonshine while His love is sunshine.
So, since God has no faith or hope, but does have love- love is greater. Grace is a variation on the word love, we are saved by His grace, His unmerited favor, through our paltry faith.
I don't know if this makes sense or not.
